Let's divide 638800 by 57
The aim is to understand the frequency of 57 in 638800.

Step 1:
6 divided by 57 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 57

Moving on to step 2:
63 divided by 57 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 6 after subtracting 57 from 63.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 57

Moving on to step 3:
When dividing 68 by 57, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 57 away from 68, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 57

Going ahead to step 4:
The number 57 fits into 118 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Deduct 114 from 118 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 57

Advancing to step 5:
When dividing 40 by 57, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1120.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 57

On to step 6:
57 can be fit into 400 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 11207.0
If we subtract 399 from 400, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 57, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11207.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 57, we get 1 and a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 11207.01
Deduct 57 from 100 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
If we divide 430 by 57, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 11207.017
Subtracting 399 from 430 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
If we divide 310 by 57, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11207.0175
Subtract 285 from 310 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
When dividing 250 by 57, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 11207.01754
If we subtract 228 from 250, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
220 divided by 57 is 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 11207.017543
If we subtract 171 from 220, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
When dividing 490 by 57, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 11207.0175438
If we take 456 away from 490, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
57 can be fit into 340 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 11207.01754385
Subtract 285 from 340 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 11207.01754385 with a remaining 5.5e-08.
